[Selective ventral derotation spondylodesis in idiopathic thoracic scoliosis: a prospective study].
Radiometric curve analysis of instrumented primary and spontaneous secondary curve correction after anterior correction and fusion of idiopathic thoracic scoliosis. ⋯ Selective anterior correction and fusion in idiopathic thoracic scoliosis enables a satisfactory correction of both primary and lumbar secondary curves. The advantage of selective anterior correction and fusion of thoracic scoliosis is the short fusion length, better derotation and satisfactory correction of the secondary lumbar curve. The disadvantages of single threaded rod techniques in terms of lack of primary stability and a kyphogenic effect have been eliminated by the development of a primary stable, small size double rod instrumentation.

Randomized Controlled Trial Comparative Study Clinical Trial[Use of peridural catheters in the treatment of postoperative pain after spinal instrumentated fusion--an experience report].
In a prospective randomized clinical study we investigated in a group of 20 patients after spinal instrumentation surgery the analgesic efficacy and the safety of epidural analgesia. Intraoperatively an epidural catheter was placed by the orthopedic surgeons for postoperative pain control. ⋯ The epidural lumbal analgesia is an effective and safe method to control postoperative pain after spinal instrumentation surgery. Precondition is the knowledge about the safe and standardized technique of intraoperative catheter placement by the orthopedic surgeon, the choice of the appropriate analgesic drugs and a good cooperation between the departments of anesthesiology and orthopedic surgery and nursing staff.

Comparative Study[Primary hip- and knee arthroplasty--comparison of the actual costs with the Australian diagnosis related groups (DRG)-].
With the introduction of the Australian DRG system in Germany the question arises which current procedures remain reasonable in cost. The present study compares the actual costs with the expected DRG reimbursement. ⋯ To cover the current costs for patients free of complications, an enormous reduction of the length of stay is required. Otherwise complicated cases may result in a loss of quality or selection of patients. The present cost analysis outlines a guideline for an individual calculation and assessment of the necessary DRG reimbursement.
